In this project, we will go over how to build a hydrogen gas sensor circuit with an arduino. The hydrogen gas sensor we will use is the MQ-8 sensor. This is a sensor that is sensitive to effects of hydrogen gas. Hydrogen gas (H2), at room temperature and under standard pressure conditions, is tasteless, odorless, […]
Simple Solar Power Light contains energy. When light hits a conductor (or semiconductor) some of the energy is translated into moving electrons, creating current. We can harness the current using solar cells (aka photovoltaic cells). When the sun shines on a solar cell, the current output is mostly constant, which is known as direct current, […]
Using the Arduino development board (http://arduino.cc) has become a very popular way to create hardware prototypes that bridge the divide between the physical world and the Internet. This article outlines how to use an Arduino, some off-the-shelf electronic parts, the Processing programming language, and Google Documents to create a push-button reference desk transaction tally device. […]
I am going to show you how you can use an RGB LED and a Cds photocell as a colour sensor for a micro-controller. I will illustrate the method to retrieve a colour using Arduino, and I will show you a how you can verify the colour being scanned with a small Processing sketch.We will be […]
Well I managed to kill my Arduino. It no longer accepted uploads with the classic out of sync error. After asking on the Arduino forum I was told I would need a high voltage programmer to rectify, so I decided just to buy a new chip. I was a bit scared about doing this but […]
Research Group: Ryan Mountcastle, Minh Trang Nguyen, Nathan Ranno, and Ryan Ward Launch: Whitworth Fall 2012 This experiment was designed to examine cosmic ray activity in the Earth’s atmosphere as altitude increases. The previous group’s project utilized three Geiger counters stacked vertically to eliminate false positives. This only accounts for rays travelling in the vertical […]
f you’ve ever wanted the ability to use some form of hardware-based authentication in your projects then this is the board to do it with. The Parallax RFID (Radio Frequency Identification) reader is super easy to configure. It only takes four wires! It uses serial protocol to transfer information from RFID cards to the Arduino. […]
The resolvent of clock synchronization over internet. by PKJ, The web−based clock management system allows you to monitor clock status from wherever they are and centrally change settings. and this small device is built with PoE technology, thus IP clocks get their time, data and power from the same network that supports your other IP endpoints. […]
